PATENT OFFICE ARTHUR BATES AND FRED RICKs. or LErCEsrER, ENItANn, ASSIGNORS T UNITED SHOE MACHINERY CORPORATION, OF rArE-RsoN, NEW JERSEY, A CORPORATION OF NEW JERSEY ATTACHMENT! OF BINDING AND LIKE STRIPS T0 ARTICLES Application filed. May 12, 1925, Serial No. 29,735, and in Great Britain June 25, 1924.

commonly known as leather bound edges, an

important object of the invention being to provide means whereby an binding of leather or the like may be applied and the abutting edges of the sheet material comprising the article secured together simultaneously by a single machine seam of sewing.

The invention is intended primarily to facilitate the production of work of the above character in which the binding strip is applied on the outside of the angle formed by the abutting edges of the materialand requires to be fastened on both sides of the angle. Certain features of the invention,

however, may be'utilized in the production of work in which the binding strip is applied otherwise than to an external angle. Also certain features of theinvention may be utilized in the production of work in which the strip is secured at one side only of the-angle.

In the specification of British Letters PatentNo. 174,419'andNo. 198,430 and in the pending United States application of the present applicant, Hicks, and Reginald B. Woodcock, Serial No. 717 ,7 69,-filed June 4-, 1924, there are described inter alia internal and external supports adapted for sewing bag edges, and a convenient construction' according to the invention from which the above and OtllGfOlOjBCtS and features of the invention will become apparent will'now'be described by way of example with reference to the accompanying drawings as appliedto'a sewing machine fitted with work supporting devices of the general nature shown in those specifications.

In the drawings Fig. 1 is a front View of an external work support provided with binding strip 1 guides and strip notching gages; Fig. 2 is a section on line 22 of Fig. 1; Fig: 31s a plan viewlooking'in the direction of the'arrow in'Fig; 2; and Fig. 4 is a perspective View of a portion of an article of work after attachment'of a binding. strip. a

As shownxby Fig.2, the upper and lower surfaces 3 and 4 of the external support for the article are at right angles to one an other, being adapted for bag, suitcase and similar work and are adjustably fixed to a stitching machine in the same way as the support 28 shown in specification No. 198,430 above referred to. The surfaces 3 and 4 support adjacent faces of the article at an inclination to and intersecting the nee-- dle path. The work is fed from the right to the left of Fig. 1, and mounted just to the right of the sewing point upon the upper and lower surfaces 3' and 4 are two stripguiding members 6 and 7 between which and the surfaces 3 and 4 a strip is guided in position properly to overlie theedge of' the work. The surfaces 3 and'4 at the right hand side of the sewing point are set back to an extent which brings the inside face of the strip guiding members 6 and? approximately in alignment with the portions" 8 and 9 of the surfaces 3 and 4 adjacent to the sewing point so that up to the sewing point the strip ismaintained out ofconta'ctwith and behind the body of the suitca'se or similar article of work. The strip 'is'primar ily guided towards correct attaching position by a guidecomposed of a rear plate 10' mounted on the machine frame and front plate 12 secured to therea'r'plate' by screws 13. This guideway formed by 'thei'plates 1O and'12 is provided with a V' notch'on'its' upper side, which notch is for the purposeof allowing a V- shaped' piece to becut out" of the strip where it passes round a corner of the work, as shown in Fig. 4. In sewing I along an edge of the work, the operator will stop. the machine when an oncoming corner of the work is opposite the-bottom of thenotch and by means of a hand knife cut out theportion of the strip within the notch. When a corner of the work is being sewn, as

described in specification No. 198,480, that I ofthe cutting knife employed. The guiding members 6 and 7 are conveniently held, as

adjustment of the screws.

shown, on to the external support by screws 18 and spiral springs 19 which press the members 6 and 7 outwardly from the angle of the support to the limits determined by This arrangement facilitates insertion of the leading end of each fresh strip used. The screws 18 may be adjusted either for strips of different widths or to permit one side of the bent strip to overlie the edge of the work further than the other as may sometimes berequired.

The extreme right hand edge of the external support is flared away backwardly at 21 to ensure free passage of the strip from the notched guide, This guide is set farther back than and at a small horizontal angle to the line of junction of the surfaces 3, 4 so as to be entirely clear of the work as the sewing is progressing.

. The apertures in the external support for the passage of the needle and awl should be arranged to support the work as closely as possible to the needle and awl; in particular the aperture in the surface 3 should have its lower edge positioned so that the awl only just clears it, the Work beingthereby supported close to the point at which the emerges after penetrating the work, and in consequence preventing any tendency of the awl to push the strip into the aperture, such tendency being most apparent, in the absence of close support, just when a notched portion of the strip is being sewn at a corner of the article. Preferably a slotted plate 22 is provided to cover the needle hole in the surface of the work support by a screw 23 which,

passes through a slot in the bent-over end of w the plate. The forward end of the plate ends in a tang, or stem, 24 wl1ich is bent rearwardly from the body of the plate so as to enter an inclined slot cut in the rib. This arrangement allows of highthwise adjustment of the plate to centralize the line of action of the needle in the slot.

To the left hand side of the sewing point the surface 3 may be set back as shown at 26 and reduced in height as shown to facilitate the maneuvering of the work in such manner that close pressure thereof against the external support is obtained at the sewing point.

' The surface 4 of. thework support is provided with a shallow groove 25 which extends "on either side of the awl hole. This groove be employed when the article to which a stripis being applied has for example curved edges or is otherwise of shape such that the lengths of the two edges of the strip when attached require to be different to conform properly to the article. a

The invention having been thus described, what is claimed is:

1. In a machine for sewing bags or like articles, means for supporting the work with adjacent faces at an inclination to and intersecting the needle path, and means for guiding an edge binding strip across the'needle path in faces.

2. In a machine for use in the manufacture of bags or like articles, the combination with means for guiding and securing an edge binding strip about the angle at the abutting edges of the angularly disposed sheets of material forming adjacent faces of the article of devices for use in notching the strip on its passage'to the attaching point.

. 3. A method of attachingan edge binding strip about the angle formed by adjacent faces position to be sewed to both of said of a bag or like article which comprises feeding the bag and strip past the attaching point and forming notches in the strip on its passage to the'attaching point, extendingfrom one edge across that portion of the strip which is to be applied to one of said faces. j

4. In a machine adapted for attaching strips to the edges ofangular articles, means for guiding the strip towards the securing point provided with surfaces defining aportion of the strip which requires to be removed before attachment.
